  • Choice of filesystem for GNU/Linux on an SD card

    - by gspr
    Hi. I have am embedded ARM-based system running on an SD card. It's currently Debian GNU/Linux using ext3 as filesystem. As I'm about to reinstall the system, I started wondering about changing to a more flash-friendly filesystem. I've heard about JFFS2, YAFFS2 and LogFS, and they all seem suited to the job. Which one would you recommend? Also, I've heard there have been a lot of ext4 improvements to better suit SSD disks; am I to interpret that as running ext4 should be just fine? What do I need to think especially about in that case? I guess the usage of the system is important. But for the sake of generality, imagine it'll do standard desktop stuff (even though it is infact a small ARM-based system). Thanks for any replies. Edit: Wikipedia tells me (in a "citation needed" statement) that Removable flash memory cards and USB flash drives have built-in controllers to perform wear leveling and error correction so use of a specific flash file system does not add any benefit. Thus, I'm leaning towards sticking with an ext filesystem.

  • Graphics Card Compatability

    - by Aaron
    I am a first time builder and while I have the basic understanding of how to put a computer together, one final thing eludes me. What are the requirements for instaling 2 or more graphics cards on a computer? Example: EVGA 015-P3-1589-AR GeForce GTX 580 (Fermi) FTW Hydro Copper 2 1536MB 384-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card ECS NGTX580-1536PI-F GeForce GTX 580 (Fermi) 1536MB 384-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card I am not planning on buying either of these cards in the near future. I simply am using them as an example because of the number of differences. As I understand it these two cards will work together (given the proper motherboard) because the only thing that matters is that they are both GeForce GTX 580. Is my assumption correct? If not, why?

  • Is it possible to upgrade HTC HD2 to Windows Mobile 7? [closed]

    - by Ladislav Mrnka
    I have HD2 over one year and I have to say it was pretty wrong purchase. Both HTC HW and MS OS (Windows Mobile 6.5) are somehow crappy. I had several crashes wich resulted in hard reset (no flashing and almost no additionally installed applications) and phone was under repair two times (2x replaced motherboard and 1x replaced dislay). After these reapirs at least HW works pretty well but OS is still bad. I would like to upgrade the phone to Windows Mobile 7. I'm not looking for some flashing (I already saw some guides). I'm ready to pay for upgrade to have it legal. Is it possible? Buying new phone just to have SW upgrade is ridiculous. Btw. My primary phone is iPhone 4 and I think on iPhone 3GS it is possible to upgrade OS iOS 4 so I would like to see similar possibility with Windows Mobile.

  • how to compare files/directories of 2 separate solaris boxes ?

    - by chz
    Hi Friends I have 2 solaris boxes and I need to check certain directories (on local filesystem and mounted nfs) to make sure that they match up on both boxes and to delete or move the other mismatches to elsewhere on the local filesystem. I investigated for unix commands like rsync, and tree but it appears that these commands are not supported on my Solaris boxes. What is the best approach to this problem with the least pain to solve it ? to use rsync, tree and then diff the outputs or find ? I have trouble limiting the find command to certain directories as there are mounted folders that contain too many xml files that I don't care to much in that directory. What's the find command to search multiple directory paths on a single find command. Thanks Sincerely

  • SQL Bits VII

    - by Tomaz.tsql
    I was very happy to dive in into SQL Bits VII. Several interesting presentations, interesting concepts, advices and most of all interesting people. Some things actually disturb me. 1. the outlook of all presentations. I would recommend to have standardized outlook of all presentations for each of the presenter. Meaning, to have a general rules of PPT design (fonts, views, etc.), general diagrams, pictures that can be used by everyone (something like techEd introduced as well as SQL PASS). 2. access...(read more)

  • Are there any downsides of 2 developers getting married ?

    - by simpson
    I remember that in my first year at college, the professor told us that his wife is also a software developer, and a few decades ago when there has been a tough period of 2-3 years in the software field they both had been unemployed and had experienced some hard times. Of course I am not asking about this economic downside, as it is a general conclusion for a family working in the same field, and is not related specifically to programming. I am asking about any other possible downsides of a family where both people are programmers. To all developers married to developers - I am not asking if it is "horrible" or something like that, of course it's not, just if there are any specific issues (all kinds of relationships has some specific issues, and at the same time are immune to others). And yes, I am asking about a male developer married to a female developer, I am clarifying to avoid jokes like "I believe that 2 developers can get married in some states" and so on :)

  • Reasons Programmers Leave

    - by Kane
    I am interested in finding out why programmers leave their jobs and if the reasons for leaving have resurfaced in your now job? Is the reason for leaving simply down to remuneration, location, I hate my boss / coworker, lack of recognition or retirement / new career path. Update: I am responsible for a team of programmers and testers and I would like to better understand what could motivate my team to leave, and hopefully try to address such issues.

  • How to hire support people?

    - by Martin
    I manage a tech support team at a mid-sized software company. We are the last line of support, so issues that we can't fix need to be escalated to the development team. When I joined the company, our team wasn't capable of much beyond using a specific set of troubleshooting steps to solve known issues and escalating anything else to the developers. It's always been a goal of mine for our team to shoulder as much of the support burden as possible without ever bothering a developer. Over the past few years, I, along with several new hires I've made, have made pretty good progress in that direction. We've coded our own troubleshooting tools which now ship with several of our products. When users have never-before-seen issues, we analyze stack traces and troubleshoot down to the code level, and if we need to submit a bug, half the time we've already identified in the code where in the code the bug is and offered a patch to fix it. Here's the problem I've always had: finding support people capable of the work I've described above is really difficult. I've hired 3 people in the past 3 years, and I've probably looked at several thousand resumes and conducted several hundred phone screens to do so. I know it's pretty well accepted that hiring good people is tough in the tech industry, but it seems that support is especially difficult -- there are clearly thousands of people walking around calling themselves support analysts, but 99%+ of them seemingly aren't capable of anything beyond reading a script. I'm curious if anyone has experience recruiting the sort of folks I'm talking about, and if you have any suggestions to share. We've tried all sorts of things -- different job titles/descriptions, using headhunters, etc. And while we've managed to hire a few good folks, it's basically taken us a year to find an appropriate candidate for each opening we've had, and I can't help but wonder if there's something we could be doing differently.

  • How can I effectively use a netbook and a desktop computer together for programming?

    - by Mana
    Currently, in my workspace, I have a netbook sitting off to the side gathering dust while I write code on my desktop. As a result, the only use my netbook gets coding-wise is when I'm writing up a quick Python script to model a given problem or concept in class; I never use it at home for coding, or for anything at all, as it is all possible and faster on my (much more powerful) desktop. I feel like this is wrong and that I should be making better use of my netbook. What effective uses have you found for a netbook and a desktop together when programming (or for software development in general)? What are the merits of this practice?

  • How to deal with "software end-of-life" situations?

    - by rwong
    When a vendor declares that they no longer intend to provide any support or services to a piece of software (and stated the intent to exit the business - offering no upgrade paths), and stated that customers must pay a nominal fee in order to have the existing data exported, what kind of recourse do programmers/customers have? Things I can think of: Need to purchase spare hardware and set up a spare environment on which the software can continue to operate. Various data export methods which do not require vendor involvement. (For example, screen scraping, printing to image followed by re-scanning, etc) Parallel systems where staff will duplicate the old data into a new system manually or semi-automatically Legal means, in case the vendor is in financial trouble Any other ideas? Assuming that there is no "circumvention" involved (no DRM, no DMCA), is data recovery or reverse engineering legal/acceptable?

  • job offer in dead technology

    - by bold
    I have a job offer in a dead technology (specific programming language) that I don't want to work with nor do I believe it will offer many jobs in the future. It requires twice a year travels abroad, which not a plus in my eyes. On the other hand the money on the table is high. What would you do? edit: as its not clear I got a job in a programming language that is different from the academic programming language I worked with. Now I see it as a mistake to head to that direction.

  • Life and Career guidance

    - by Andrei TheGiant Haxtor
    Hello programmers. I have a current dilemma I'm pondering over. I will be graduating from high school with ~60 credits worth of community college work (pre-engineering courses), and I am wondering what would experienced programmers suggest I do with my time since I have all of the bull courses out of the way. Should I start taking computer science/engineering courses or should I take some other courses that interest me?(psych, math) The reason I am asking this is, well , I like doing a lot of self studying, especially relating to software and tech. I don't like to have the pressure of hard classes on me, so I could make up for the time lost doing the CC courses and dive deep in programming and books. I've started getting into programming recently unfortunately, since I didn't have much time b/c of my course load. Right now I am doing Java and messing around with android. I would like to get involved in web&mobile development, operating systems, and finance software. If any of you experienced people could please give me some guidance and words of wisdom, I would greatly appreciated. Sorry that this isn't necessarily related to programming. All the best.

  • Difference between '\n' and '\r\n'

    - by sukhbir
    Yes yes, I am aware that '\n' writes a newline in UNIX while for Windows there is the two character sequence: '\r\n'. All this is very nice in theory, but my question is why? Why the carriage return character is extra in Windows? If UNIX can do it in \n why does it take Windows two characters to do this? I am reading David Beazley's Python book and he says: For example, on Windows, writing the character '\n' actually outputs the two- character sequence '\r\n' (and when reading the file back, '\r\n' is translated back into a single '\n' character). Why the extra effort? I will be honest. I have known the difference for a long time but have never bothered to ask WHY. I hope that is answered today. Thanks for your time.

  • Kubuntu login problem

    - by Balázs Mária Németh
    I have a problem when trying to login to my Kubuntu 10.10. The login screen shows up, then I type my password, a blank screen is shown with my desktop background picture and then throws me back on the login screen. if I choose to login from console, I can do that, and by typing startx I can log in just fine but in the end I cannot shutdown the computer from the k menu nor will my settings remembered for the next time I log back. I have my home directory mounted from a different partition but I tried to create a new user account and I could log in without any kind of problem. The home directory is not encrypted, at least not to my knowledge. Some log files: Xorg.0.log dmesg.out kdm.log xsession.errors

  • Importing PKCS#12 (.p12) files into Firefox From the Command Line

    - by user11165
    I’ve posted this question up on #Ubuntu and #Firefox Forums, and really could do with some help.. Anyone know where i could look or help with the answer. I’m hoping the power of social media will come through… I have a need to perform the following action: Firefox 3.6.x: Quote: open Edit - Preferences - Advanced - Encryption - View Certificates - Your Certificates - Import However i need the same functionality from the bash command line. So far I’ve established that the following command is supposed to be used: Quote: certutil -A -t “u,u,u” -d /home/df001/.mozilla/firefox/qe5y5lht.tc.default/ -n “mycert” -i client.p12 This executes with no isses, however, doesn’t show up in any Firefox Certificate store. However, I have noted that prior to running this command, i have a cert8.db key3.db and secmod.db file in the above folder. After running the command the certutil seems to have created a cert9.db, key4.db and pkcs12.txt file Listing the contents using the command: Quote: certutil -L -d sql:/home/df001/.mozilla/firefox/qe5y5lht.tc.default/ does seem to confirm my attempts of importing files into a certificate folder of some kind have worked. because i get Quote: Certificate Nickname Trust Attributes SSL,S/MIME,JAR/XPI Thawte SSL CA „ Go Daddy Secure Certification Authority „ Thawte SGC CA „ Entrust Certification Authority - L1C „ My Nero CT,C,c mynero P„ davidfield - Internet Widgits Pty Ltd u,u,u So, having tried this, and heading back over to the www, i cam across this command: Quote: pk12util -d /home/df001/.mozilla/firefox/qe5y5lht.tc.default/ -i client.p12 -n “David Field” -P “cert8.db” this again, appears to be importing something somewhere, however, again, Viewing certs from the Firefox interface doesn’t show the imported Cert. I’m surmising here on reading that the certutil and pk12util are creating a new NSS database, which firefox isn’t reading. So my question is, how can i get the p12 cert from the command line so it displays in the firefox Certificate manager interface? Why have i posted this here? Why not post on the firefox forum? Well i will copy and post the same question there as well, however the ability to use the command line to do this is important, as I have potentially 2000 machines which will need a user cert imported into firefox via a p12 file. I need to do this in the form of a script, i thought the hard part was going to be making the p12 file from the microsoft 2003 CA, turns out thats easy. I can’t just import via the GUI and copy over cert8.db x 2000, i can’t ask users to use the CA webinterface as its for VPN access, the users are off site, and they need the VPN to get to the cert server.. Is there any person out there who can help? By the way, i don't have the tor buttun installed.

  • How to remove username from "Me" menu (right near to power button on the top panel)? [closed]

    Possible Duplicate: How do I replace the MeMenu username with my actual name? My user name takes approximately as long as would 6 icons. I don't need to see my username, I am the only user of my computer. How can I remove it? I use Ubuntu 10.10. UPDATE: The answer found: gconftool -s /system/indicator/me/display --type int 0 UPDATE: Unfortunately the solution doesn't work any more. Now it totally removes the instant messaging menu (including the icon) instead of just removing a name.

  • Ubuntu 10.04: boot error for custom compiled kernel - gave up waiting for root device

    - by atharva
    I have installed lucid on my Lenevo Laptop (Y 410 series , x86 platform) and it is working fine. Now I have compiled kernel 2.6.37 downloaded from the kernel tree. I followed usual procedure of compiling kernel (make menuconfig, make, make modules etc). Then I created the initrd image using mkinitramfs and updated my grub using update-grub command. update-grub detects the initrd image of the compiled kernel. However when I boot from this kernel it gives me following error: Gave up waiting for root device. Common problems: -Boot args (cat /proc/cmdline) -Check rootdelay= (did the system wait long enough?) -Check root= (did the system wait for the right device?) -Missing modules (cat /proc/modules; ls /dev) ALERT! root=UUID=/... does not exist and then it falls onto initramfs prompt. I have tried following solutions discussed in different Ubuntu forums: disable uuid and point root=/dev/sda8 (sda8 is where my kernel image resides (both default kernel and compiled one) from /etc/default/grub compile kernel using CONFIG_DEVTMPFS=y suggested here Still I am unable to boot from the compile kernel. Could someone please suggest me the solution?
